The weather forecast around the new moon was exceptionally good at the HAS site. An unplanned trip took me there again after 10 months or so and rewarded another galaxy target back. Met quite a few folks at the facility while respectfully observing the social distance.
Though having spent 2 nights in a row, the second night encountered a cold front from the north. People staying awake not only to wait for the clear up, but also worry about getting worse. In short, what if L could be doubled, would there be more details around the rim? I think so.
Technically, this is the first time I uploaded an LRGB target with Chroma L and B filters. I used to use Astrodon's however they have the blue cut at 390nm that has obviously shown bad coma on my setup. Chroma makes it at 420nm and the result is way better.
I had another try of M104 two years ago and it could be found
here.
